' Inthe accompanying drawings, illustrating thisinvention, Figure 1 is a side view of thc spindle-tip mounted on the spindle. Fig. 2' is atransverse section'al'view of Fig. 1 through the linear: m, and Fig. 3:is a transverse sectional view through the line-y y. Fig. 4 is a detached view of the spindle-tip and the end of the spindle. Fig. 5 is aview of a modified construction of the spindle-tip mounted on thespindle, and Fig. 6 is a view of the blank before it is folded and bent toform the spin-' dle-tip'.

The spindle-tips used with spring shade rollers consist of an outer fiat 'endl, adapted to fit into and engage with the. elongated opening in one of the supporting-brackets by which the spindle is held stationary as the IOllBl'lIBVOlVGS around it, a middle portion 2, consisting of recesses or notches with which the pawls on the roller engage, and an inner portion 3, by which the tip is attached to the spindle B. Heretofore these 'spiudl'e tips have usually been cast from metal and as thus made areapt to be imperfect and to vcause an imperfect operation of the roller. ,In thisinvention the spindle-tipis made of sheetmetal foldedin a novel manner, so. as to form a tip of an improved and more perfeet construction and shape. As will be: seen from the. drawings, the sheet-metal blank, Fig. 6, from which the tip ismade is folded longitudinally upon'itself by means of suitable dies in three folds or parts in such mannor that across-section through thecenter of 150 the; tip will show, Figs, 2 and. 3, two outer UNITED STATES*-P*ATENT- OFFIQE...

= folds 4 4, connected by a transverse interior web-5, At the outer end of: the tipthese three folds are brought close together and united to form a solid flat. end 1, which engages with thebracket. Beyond; this fl atendfs the folds open outor widen to-formtheratchetsection 2 of the tip. In, this section the ratchet or notch with which the toe of'the pawl engages isformed by the edge 6' of the outer folds 4, Fig.3. Inthe operation of the roller the pawl slides-over the rounded edge 7 of the. fold 4 where it joins the web. 5 and dropping into the recess, formed by thefold strikes against and engageswiththe. outer edge 6. As the transverse,-connectingweb 5 is; diagonal in cross-sectiomand henceas therecesses formed by th e; foldsopen. in. opppsitedirections, one is always upand in a posltion to engage with thepawls with eachhalf-revolution of the roller. The inner or attaching end 3 of the tip beyond the-ratehet seetion 2 widens or opens sufficiently to receive the end of the spindleB and fit over the circumference of the latter. As will thus be seen inthis iin' provement, the spindle-tip-is attached tothe 7 5 outside of the wooden spindle-,theout'er folds 4 being curved to conform to the circumference of the-spindle, and the necessity of boring a hole inthe end of the spindle or preparing the spindle in any manner toreceive the tip is done away with, The inner ends ofithe curved folds 4 project beyond the connecting trans verse web 5, and in the, construction shown in Figs. 1 to 4 are provided with holes.8,through whicha pin or rivet 9 passes to secure the tip on the end of the spindle. To. place the tip on the spindle, it is only necessary to insert the end of the spindlewithin the outer 'folds4' of the tip, which project beyondthe "web5, until the end of the spindle rests,

against the edge 12 of the web. A pin or rivet is then driven through the holes Siin, the tip. and through the endof thespindle,

when the parts are securely attached toeach, other. To secure or tiethe endiof'thespring 9 5;

10- to the spindle, it is: passed througha hole. 11 in ornear the edge 7 of the fold 4 of. the tip and ben'taround the; latter-ps0. as to. be.

' securely fastened; Inplaee of; securing the,

tipbya pin Qanyot her suitable metl'rod' off 19o;

attachment may be used, as. the edge 13 of the fold 4; maybe driven into the wood of the spindle, as shown in Fig. 5.

As will be readily understood, a spindle-tip made as described herein can be more accurately and perfectly constructed than when cast, as the parts are bent and shaped by dies, and when attached to the spindle on the outside of the end of the latter it is unnecessary to make any hole in the end of the-spindle to receive the tip, and the attachment of the tip on the spindle is more perfect and always in alinement with the spindle itself, and, further, the outer-.member 1, being formed of three folds united into a solid flat end, is firm and strong for the purpose desired.

iVhat I claim isl. A spindle-tip for spring shade-rollers composed of sheet metal folded sidewise in longitudinal folds and bent into form, comprising an outer flat section, adapted to engage with the bracket; a ratchet section adapted to receive and engage with the pawls on the roller; and an inner section arranged to fit over the spindle, substantiallyas described.

A spindle-tip for spring shade-rollers composed of sheet metal folded longitudinally; andbentinto-fo'rni, comprising an outer fiat section 1v adapted to engage with the bracket; a ratchetsection, consisting of the outer folds 4 joined by the transverse Web 5, and'adapted to engage with the pawls on the roller; and an inner section formed by the folds 4 arranged to fit over the spindle, substantially'as described.
